Description

[0001]
(Technical field)
The present invention relates to an apparatus for separating packs of laminated products, such as packs of paper napkins produced by a folder, from each other. The invention also relates to a method corresponding to separating packs of laminated products from each other, as well as to a folding machine incorporating the device and performing the method.
[0002]
(Background technology)
From International Patent Application WO-A-9728076 it is known with respect to dividing piles of laminated products and separating the packs from one another, the device comprising a path for piles of laminated products, Along the traveling path, a pair of guides define individually closed paths along which the pair of separator fingers are advanced. Each guide has an advance stretch and a return stretch, at least the advance stretch being essentially parallel to the path of the pile of the laminated product. In order to separate two adjacent packs of product from each other in the unloading area, this known device is used while stopping the finished pack so that each pack can be separated and unloaded separately. In the unloading region, it is considered to be a system that temporarily separates two fingers forming each pair. In this way, the foremost part of the pile is removed from the next. This known device is particularly effective, easy to assemble and is particularly reliable compared to previously known devices. However, the mechanism that separates finger pairs and napkin packs in the unloading area requires proper and periodic maintenance interventions to remove dust that can lead to failure in certain work situations.
[0003]
It is an object of the present invention to provide a device that is simpler and more reliable than conventional devices.
[0004]
(Disclosure of the Invention)
The above and further objects and advantages will become apparent to the expert from the following description, which is basically achieved by the device, in which the separator fingers (in this case single and not double) slide. A separation member is provided that allows insertion and extraction operations on the pile of product moving forward along the travel path near the end of the travel stretch. The movement of the separating member is activated simultaneously with the movement of the product along the path of travel, so that the separating member is inserted between two successive packs of laminated product and individual separator fingers are inserted between the packs. . In this way, the separating member can temporarily suppress the pile of the laminated product and move the separator finger away from the travel path to lower the first pack of piles. At the same time, a holding member for holding the front surface of the pack is brought next.
[0005]
Basically, according to the present invention, a method of separating adjacent packs of laminated products can be used, which is:
Temporarily inserting a separating member between one pack and the next pack with separator fingers in between;
Separating the pack and the next pack, releasing the separator finger and stopping the next pack by a separating member;
Bringing forward holding members, eg moving blades, before the next pack;
Sliding out the separating member;
Is included.
[0006]
The resulting device is simpler and more reliable than previously known devices. In previous devices, a single separating member (or else two symmetrical separating members set on both sides of the path) is in a fixed position with respect to the direction of travel in which the production takes place, In combination with the separator finger, the function previously performed by the pair of fingers is performed. In this way, the number of components of the device is reduced and, for example, the plants that manufacture this type of paper article can eliminate the interactive parts that can become clogged due to the large amount of dust that is often present.
[0007]
Further advantageous features and embodiments of the invention and methods according to the invention are described below and are defined in the appended claims.
[0008]
(Best Mode for Carrying Out the Invention)
Knowledge of the invention will be gained by understanding the description and accompanying drawings that illustrate possible, non-limiting embodiments of the invention.
[0009]
In the accompanying drawings, and with particular reference first to FIG. 1, reference numerals 1 and 3 indicate two folding rollers of a folding machine forming a pile P of a napkin or another folded laminated product. Folding rollers 1 and 3 rotate around two vertical axes A and B and have annular grooves 1A and 3A, in which arched arms 5 and 7 enter, folding material Are pulled away from each roller and the material is pushed out of the machine against the pile P of product already formed. The continuous web-like material N can be folded along an extension line and fed into a nip defined between two rollers 1 and 3, in connection therewith known types Systems are known, which once circulate around rollers 1 and 3 fold the material exiting the nip to produce a pile of material folded into a zigzag shape. At each fold, the individual arched arm 5 or 7 pulls the material away from the roller and presses it against the pile P already formed.
[0010]
The operation of the folder described briefly above is known per se and is therefore not shown in detail here.
[0011]
The pile P of folded web-like material is pushed against the transverse blade 9 that cuts into two parts P1 and P2, each part forming a plurality of napkins folded in two or four. A dividing wall is set below the blade 9 and holds the two parts P1 and P2 obtained by cutting the pile separately from each other, allowing independent handling of the two parts.
[0012]
Pile P, P1, P2 is a pair of side walls 11 (see FIGS. 5, 7, and 8) and napkin packs M1, M2,..., Mn each containing a predetermined number of products, The bottom wall 12 is advanced and lowered along a defined path by a limited supply channel.
[0013]
In order to separate one pack of napkin M1 from the next pack M2 at the side of the supply channel for the piles P, P1, P2, two sets of separator fingers 15 are set, one on each side of the channel. Each separator finger 15 is incorporated in an individual slider 19 that slides on an individual slide guide. The configuration can be seen in particular in FIGS. Corresponding slide guides 23 are set on each side of the supply channels for the piles P, P1 and P2, and the slider 19 of the separator finger 15 slides inside the slide guides 23, and the slide guides make the slider 19 easy. It is closed at the top by a plate 25 made of a material with a low coefficient of friction so that it can slide. Each slide guide 23 has two rectangular stretches rounded by arcuate end portions near the folding roller and near the area where the stack of laminated products is unloaded.
[0014]
The slide guide 23 defines a seat that fits inside the inner rectangular stretch, i.e., closest to the supply channel for the napkin pile, to fit the bottom teeth 19X provided on the slider. It fits in the drive belt 24 of a cross section. In order to control the movement of the fingers 15 and the slider 19, the belt traveling speed is adjustable, which is approximately equal to the traveling speed of the product pile P.
[0015]
Further, the belt 24 may not be used, and the slider 19 can be directly fitted into the fixed slide channel having a low coefficient of friction, which forms the slide guide portion 23. In this case, the advancement of the slider is performed by the thrust force applied by the pile of the laminated product.
[0016]
Each slider further includes a rear appendage 19A for the purposes described below.
[0017]
The guides 23 define a closed path, preferably the same number of sliders 19 are set in each of the guides 23, and each of the supply channels is associated with each slider 19 and the guide 23. Corresponding to the finger 15, on the opposite side of the supply channel for the laminated product, there is a slider 19 and an associated finger 15 in the guide 23.
[0018]
In the region corresponding to the two arcuate end regions of the guide 23, there are individual first grooved spools 31 with a set of elongated grooves 31A (near the individual folding rollers 1, 3), There is a second spool 33 (in the unloading area).
[0019]
The two hooks 33A are axes parallel to the rotation axis of the spool 33 and are hinged to the spools 33 (see particularly FIG. 2). The hooks are elastically loaded by springs 33C. Protrudes from the circumference of the. The hook 33A is fitted to each slider 19 by the attachment member 19A, and the attachment member is provided at the rear portion of each slider 19 (that is, the portion opposite to the separator finger 15).
[0020]
With the above configuration, the first grooved spool 31 is rotated stepwise clockwise as indicated by the arrow f31, so that the rear attachment member 19A of the slider 19 is hooked on the groove 31A. From the individual outer rectangular stretches of the guide 23 to the inner rectangular stretch, ie the stretch facing the pile of the product. The gradual rotation of the fluted spool 31 can be performed using a suitable system, for example using a free-wheel mechanism operated by a linear cylinder piston actuator, or otherwise using a rotary actuator. it can. Similarly, by rotating the second spool 33 stepwise in the direction indicated by the arrow f33, the slider 19 and the finger 15 integrated with the slider 19 are hooked, and the individual guide portions 23 are separated from the internal rectangular stretch. To the outside rectangular stretch.
[0021]
On each side of the supply channels for the piles P, P1, P2 of the product, a continuous flexible member 35 is deployed in parallel with the external rectangular stretch of each guide 23, and the flexible member passes through two pulleys. And bristles fitted into the fingers 15, which are moved by the second spool 33 to the external rectangular stretches of the individual guides 23, opposite to the direction of travel of the piles P, P1, P2 of the product. Is drawn along the direction indicated by the arrow f35. The sliders 19 are supported by the flexible member 35 until they contact the first spool 31 as seen in FIG. A large number of fingers 15 are caused to collide against the spool 31, and the flexible member 35 can slide under the fingers by deforming the bristles provided on the members. During each rotation of the first spool 31, the fingers that collide with it are pushed by the member 35 and remain in contact with the spool itself. The number of fingers 15 that are set and waiting for the spool 31 is the size of the pack of products M1 to Mn formed: the size of each individual pack, the size of the pair of fingers 15 waiting Depends on the number.
[0022]
In the vicinity of the end area of each guide portion 23 (area further away from the folding rollers 1 and 3), a separating member generally indicated by 101 is set, and the separating member is arranged in the traveling direction of the product pile. Do not move, do the horizontal movement of the insertion and withdrawal associated with the pile itself. As will be apparent from the following description, this movement occurs simultaneously with the movement of the separator fingers 15 so that each pack of product can be temporarily stopped, separated and lowered.
[0023]
Each separating member 101 (see in particular FIGS. 2 and 3) comprises a stem 103 incorporated in a rod 105 of a cylinder piston actuator 107, which controls the reciprocating movement indicated by the two-way arrow of the stem 103 itself. To do. During its own movement, the stem 103 is guided by a groove 109 formed in a support element 111 fixed with respect to the guide 23, and a cylinder piston actuator 107 is incorporated in its attachment member 113.
[0024]
The operation of the device is described below.
[0025]
The folding rollers 1 and 3 rotate continuously to form a pile P, which is cut into two parts P1, P2 by a blade 9. At this stage, individual separator fingers are kept waiting at positions adjacent to the rollers 1 and 3 while being kept out of the lamination region. When the predetermined number of stacks is reached, i.e., as a result of the cutting action performed by the blade 9, when the napkin reaches the predetermined number, each grooved spool 31 rotates on each side of the machine in a single step, and thus the slider 19. Naturally, each separator finger 15 is brought into a further advanced position with respect to the point at which the next lamination of the web material N is formed from the extraction position outside the folding roller in the lamination area. This movement is made possible by providing the folding rollers 1 and 3 with an annular groove. The slider 19 is generally released from the grooved spool, and along with the bottom attachment member 19X, in each extension seat of the belt 24 provided on the guide 23, along the stretch of the road facing the supply channel. Inserted.
[0026]
When the supply of the web-like material N continues, i.e. due to the accumulation of the material folded into the pile P, when it is folded, the two fingers 15 on the two sides of the supply channel cause the individual grooved spools 31 is drawn along the side of 31 to the folding action area, where one fold and the next fold remain connected, proceeding along the guide 23 and proceeding with the action of the arm 7 Pushed by the piles P, P1 and P2 of the product itself, where it is assisted by the action of the individual drive belts 24, so that the speed of travel (as described above) is the speed of travel of the pile P Almost equal.
[0027]
When the two sliders 19 on the two sides of the supply channels of the piles P, P1, P2 reach the end of the rectangular stretch of the guide 23, the first group of laminated products or napkins M1 is paired with separator fingers. 15 and separating member 101 are separated from the next group M2 in the manner illustrated in FIGS. 4A-4D, where one side of the supply channel for the napkin pile is shown. On the opposite side, the symmetrically configured members perform a symmetric continuous operation. In FIG. 4A, the separator fingers 15 are set between two packs M1 and M2 of products and travel with them in the direction indicated by the arrow F. The stem 103 is in the extracted position, that is, pulled under the support portion 111.
[0028]
In FIG. 4B, the separator fingers 15 set between the packs M1 and M2 are aligned with the stem 103 of the separating member 101, and the separating member is inserted between the two successive packs M1 and M2. The two continuous packs are separated a little by being pulled out by the cylinder piston actuator 107 in a timely manner and the separator fingers 15 coming out. As can be seen in FIG. 4C, the spool 33 is now rotated to a first angle and hooked on the rear appendage 19A of the slider 19 by one of its hooks 33A, which is set between the packs M1 and M2. The fingers 15 are combined, and the slider 19 is moved away from the position where the stem 103 is disposed at a certain angle. During this stage, the hook 33A wins back against the force of the spring 33C, and in that way, the slider 19 and the finger 15 can approach the axis of rotation of the spool 33, making it even easier from the napkin pack. To be released. The thrust force is obtained by an inclined rounded contour portion 26 acting on the slider 19.
[0029]
The second hook 33A supported by the spool 33 is subjected to the same rotation and carries the slider 19 previously removed from the unloading area of the napkin in this manner to the external rectangular branch of the guide 23, along which the slider Is pulled again until it reaches the grooved spool 31 so that it can be reused. The return of the slider 19 along the external rectangular branch of the guide 23 is obtained by the flexible member 35 in a manner known per se.
[0030]
FIG. 4D shows a further step (partially overlapping the previous step), after the blade 81 or another suitable forward holding member of the pile has been inserted into the napkin pile path, the stem 103 is I'm pulling in. The mechanism for insertion of the blade 81 is illustrated in FIG. 5 and will be described in more detail below. In this method, the front of the napkin pile is stopped by a blade 81, which travels along the path of the napkin as described below, allowing the stem 103 to return and release the napkin pack. . The blade 81 advances until it hits the front of the product pile against a vertical contrast surface. The vertical contrast surface also serves to accommodate the product, and by swinging around a horizontal axis perpendicular to the direction of product pile travel, a part of the means for turning the individual packs of products upside down and down is provided. Make it. The purpose of rocking is to unload individual packs of products, as described below.
[0031]
Means for turning over and unloading individual packs M1, M2 .... Mn of the product are illustrated in particular in FIGS. 5 to 8 and described in detail in the international patent application WO-A-9728076, They are basically equivalent and their contents are included in this description.
[0032]
The wall 12 defining the bottom of the supply channel for the piles P, P1, P2 is stopped by a comb-shaped portion 12A, which is supported by a bracket 43 articulated at 45 with a block 47. It cooperates with the moving surface defined by the laminate 41A. Each bonded article 41A has a slot 41, and a bar 49 orthogonal to the surface 41 is fitted in an adjustable position therein. A plurality of bars 49 are aligned with each other to define the vertical contrast surface that also functions to receive a pile of products.
[0033]
The surface 41 formed by the bonded material 41 </ b> A can be turned over around the horizontal axis 45 by the cylinder piston actuator 51. In addition, the block 47, together with the plate 53, the actuator 51 and the surface 41, can be moved with respect to the directional arrow f47 by the mechanism shown in FIG. 7 (which is known per se and will not be described in detail here). it can.
[0034]
A blade 81 is set on the surface 41 and is operated by the mechanism shown separately in FIGS. 5 and 6, for example. The blade 81 is forced to act on the spindle 83 which develops in parallel with the direction of travel of the piles P, P1, P2 of the product, and in such a way, itself is integrated with the spindle, Shake around. The spindle 83 is forced against the cylinder piston system 87 by means of an arm 85, the cylinder piston system having a top position extracted with respect to the piles P, P1, P2 (shown in solid lines in FIG. 5) In order to cause the blade to swing between the bottom position (indicated by the dotted line in FIG. 5) where the product pile rests on the blade itself, the spindle is controlled to swing on its own axis.
[0035]
In addition, the blade support 81 </ b> A (FIG. 6) is forcibly applied to the stem of another cylinder piston actuator 89 that displaces the blade 81 in a direction parallel to the traveling direction of the pile P.
[0036]
The arrangement described here is symmetrical and comprises a pair of blades 81 set side by side, protruding from the machine at a position corresponding to each part P1, P2 of the product pile.
[0037]
The operation of unpacking the product pack is performed as follows.
[0038]
The bars 49 are first brought to the position where they are closest to the folding rollers 1 and 3, and the most advanced product in the piles P, P1, P2 rests on the bar 49 and pushes against them. . When the web-like material N is folded and the napkin is formed by the rollers 1, 3, the blades 9 are moved by the control of the motor 61 in order to provide a room for the new product 49 leaving the machine.
[0039]
When the pair of fingers 15 reach the position of FIG. 4, a sensor (not shown) sends a signal. This signal can initiate a cycle for the unloading of the napkin pack M1, which is performed as described below. The stem 103 is inserted into the gap between adjacent packs for separation by the fingers 15 at the most advanced position along the product supply channel. The integrated finger 15 and the slider 19 are separated by the rotation of the spool 33. The blade 81 is lowered and penetrates into the created empty space. The overall process corresponds to that already described with reference to FIGS. 4A-4D. In order to send the pack M1 to the conveyor 91 (FIG. 8) composed of a plurality of parallel belts, the surface 41 is rotated 90 ° by the cylinder piston actuator 51, and a bar 49 corresponding to the bonded material 41A is provided between the belts. pass.
[0040]
The next pack M2 is stopped forward by the stem 103 and stopped by the blade 81 after the blade is inserted by the circumferential movement of the stem 88.
[0041]
When the pack M1 is accumulated on the conveyor 91 and removed from the unloading area by the conveyor 91 itself, the actuator 61 moves the assembly 41, 43, 47, 49 to a position where it contacts the front surface of the pack M2. While the surface 41 is raised again by the cylinder piston actuator 51, the surface 41 is raised again by the cylinder piston actuator 51. In the meantime, the blade 81 is pushed forward under the thrust force of the product pile, so that this position is in the web as long as the continuous operation of the folding machine can be operated continuously without a substantial increase in product compression. The thickness value of the green material N and the production rate are determined by the PLC that controls the actuator 61. The surface 41 and bar 49 are pulled out of the stem of the cylinder piston system 89 by the finger 15 being pulled out by the spool 33 (FIG. 4D) before they return to the position where the previous pile is stationary. Under the thrust force of P, only the blade 81 that freely moves is stopped at the final stage.
[0042]
When the bar 49 again contacts the first napkin of the previous pile, the blade 81 is slid up by the actuator 87 and pulled into the initial position by the actuator 89.
[0043]
Referring to the accompanying drawings, the actuators and devices that can unload the product pack are double and symmetrical, so that the unloading of the pack M1 consisting of two parts P1 and P2 that cut the pile P is I can't do it at the same time.
[0044]
In the described range of embodiments, the stem 103 of the separating member 101 is moving perpendicular to the direction of travel of the product and substantially parallel to the axis of the stem itself. In the case of certainty, the stem 103 is advantageously inserted as close as possible to the position where the separator fingers are arranged between adjacent packs of product. For example, it is advantageous if the product is made of a very elastic material so that it is easy to access the separator fingers without losing enough space for the insertion of the stem 103.
[0045]
In such a case, it is clear that the separator finger 15 and the slider 19 have a guide groove within the range in which the stem 103 slides during operation for insertion between adjacent packs of product. . When the end of the stem 103 is inserted between successive packs of product, the stem 103 can be raised so that it is released from the slider 19 as well as from the fingers 15.
[0046]
One way to obtain this action is to properly form the fingers 15, as shown in FIGS. 9A-9C and 10A-10B, in which the stem 103 is also used for insertion operations. Are in different positions. FIG. 9A shows the slider 19 together with the separator finger 15 integrated therewith, and is partially shown in cross section to show the guide groove 15X. The guide groove 15X terminates in a protruding tooth shape end portion or a curved region connected to the toe 15Y. FIGS. 9B and 9C illustrate how the stem 103 is guided along the groove 15X until it hits its end, i.e. a round curve. The sequence of stem advancement moves it up the end portion or tow 15Y, so in fact the stem 103 is raised and released from the guide groove 15X as shown in FIG. 9C. In this position, the separator finger 15 can be removed by the spool 33 in the manner described above, while the stem 103 is maintained until it faces the second pack of laminated product. FIGS. 10A and 10B show cross sections taken along the plane indicated by lines XX in FIGS. 9B and 9C, respectively.
[0047]
The raising action of the stem 103 can be obtained by bending the stem itself or else by attaching the stem with a corresponding actuator 107 to allow the stem to swing in a vertical plane. is there.
[0048]
Inevitably, the release from the guide groove 15X is done in a different way, for example by another actuator or by a cam profile which is outside the area of the finger 15 and the slider 19, so as to raise the stem 103. I can't disturb you.
[0049]
The return path of the separator finger can be developed at different levels, preventing the stem 103 and the finger from colliding at the return stage. The stem 103 can also be suitably shaped with a double Z-curve, with the distal region at a low level, corresponding to the level of the separator finger 15 inserted between adjacent packs of product. , And the proximal region for the actuator 107 is at a high level so that it is not disturbed by the passage of the finger 15 in the return path.
[0050]
When the lifting action of the stem 103 is unnecessary, the insertion of the product into the gap between adjacent packs at a position corresponding to the overall dimensions of the separator finger 15 is illustrated in FIGS. This can be done with differently shaped fingers themselves. In this case, the top surface of the separator finger 15 is formed in a step shape. The step also forms a groove 15X for guiding the stem, even if it is open on one side. The stem 103 is inserted into the lowered region of the separator finger. The separator finger 15 can be separated after the insertion of the stem 103 by the step shape of the finger itself without moving the stem in the vertical direction, and its advancing operation is indicated by an arrow in FIG. 11 also shows a possible Z shape of the stem 103.
